Problems solved by technology

However, TVs currently on the market (especially TVs using new display devices, such as LCDTV, PDPTV, DLPTV...) cannot display high-quality displays due to various problems.
[0003] Sometimes people often want to adjust some specific display colors locally, such as human skin color, blue sky, green grass, etc., but most of the existing TV image adjustments only provide changes to the overall color, for example, Adjust the red, green, blue display components of the whole screen, etc., so that the adjustment is often "touching the whole body", which cannot meet the change requirements for specific preferred colors

Embodiment Construction

[0013] The TV image preference color space conversion method comprises the following steps: first, select the color range to be processed, the color range to be processed includes brightness range, hue range and saturation range; then set the target corresponding to the color range to be processed Color range; the target color range has the same brightness as the color range to be processed, and is obtained by adjusting the hue and saturation of the color range to be processed. Detect the color information of each pixel in the input image signal, and convert it to the corresponding target color range when it belongs to the determined color range to be processed, such as figure 1 As shown, the processed image signal is then output. If it does not belong to the determined color range to be processed, no processing is performed.

[0014] Specific implementation example: the brightness, saturation, and hue setting ranges of the color range to be processed are all 0 to 31.75 (the ...

Abstract

This invention discloses a conversion method for the favorite TV picture color space including the following steps: first of all, selecting the armed color sphere including a brightness sphere, a tone sphere and a saturation sphere, then setting corresponding target color sphere to test the color information of each pixel in the input image signals and convert it to the corresponding target color sphere when it belongs to the armed color sphere then to output the determined processed image signals.

Description

【Technical field】 [0001] The invention relates to a TV image processing technology, in particular to a TV image preferred color space conversion method. 【Background technique】 [0002] In recent years, the development of digital TV broadcasting has been very rapid. The United States, Japan, Europe and other developed countries have entered the stage of fully implementing digital TV broadcasting. The United States is not only committed to increasing high-definition digital TV programs, but also decided to completely stop broadcasting analog TV, while many large and medium-sized cities in my country have launched cable high-definition digital TV, and at the same time, it is determined that analog TV will be completely stopped in 2015. Since the transmission of digital TV will hardly damage the program quality, the user can get the signal quality almost equal to that of the studio at home. However, the TVs currently on the market (especially TVs using new display devices, such ...
